Can I use high-density floppies with the A1200s normal disk drive?
A. Not reliably! The high-density disks need a stronger magnetic field from the disk heads to reliably write to them. A high-density drive does this automatically, but the A1200’s double-density drive can’t. Writing high-density disks with a double-density drive will result in erratic operation of those disks. They may work fine for hours, days, or weeks, only to fail when you need them most. Use double-density disks with Amiga double-density (880K) drives, like the one built into the A1200, or get an external or internal high-density Amiga drive.
